Room PreparationDuring the design of the data center, consider ease of entry for the equipment, floor loading factors, andaccessibility to piping and wiring.

Seal the room with a vapor barrier to minimize moisture infiltration. (Polyethylene film is recommendedfor ceiling and wall applications.) Apply rubber- or plastic-based paints to concrete walls and floors.

Insulate the room to minimize the influence of exterior heat loads. Use the minimum required amount offresh air for make up to comply with local and national codes and regulations. Fresh air imposes extremeload variation on the cooling equipment from summer to winter and causes increased operating costs.

The equipment is designed as a sensible cooling air conditioning unit for in-row use in data centers. Theequipment does not have humidification or dehumidification control. Room humidity must be withinacceptable operating conditions before starting equipment. If operated in spaces where the humidityis in the unacceptable operating conditions section of the Operating Guidelines chart (see the InRow RCOperation and Maintenance manual) the equipment condenses excess water vapor from the air. This willexceed the pumping capacity of the condensate pump, causing the equipment to send an alarm and shutdown to avoid overflowing the condensate pan. The condensate pump runs until the fluid level in the panis reduced, and the alarm is automatically reset. The equipment self-regulates in this manner until normal

operating conditions are present.

Note: The InRow RC is not intended to be used in an occupied office environment, due to potentially high noise levels during peak loads. Install the InRow RC in a computer roomwhere people are normally present only for maintenance.

Incoming power supply requirements

See the electrical rating label on the equipment to determine the maximum possible current draw of theequipment. Provide either a single outlet circuit or a Power Distribution Unit (PDU) with sufficientcapacity to handle all loads. Do not plug two InRow RC units into the same branch circuit or PDU.

The equipment must be grounded. Electrical service must conform to national and local electrical codesand regulations.



Piping DiagramsWith cooling distribution unit (CDU)

Note: Install isolation valves and particulate strainers with 20 mesh stainless steel screen(opening size = 865 micron) in the supply line between the chiller and the CDU. If the system

is to be set up as an isolated loop - a chiller and pipe layout, dedicated only to supplying RCunits and no other equipment - the strainer may be placed in the piping circuit before the pump.Thoroughly flush the system to remove all debris and process chemicals.

Note: Top or bottom entry can be chosen individually for each type of connection, i.e. power,condensate drain, humidifier water supply, chilled water supply and chilled water return. Top

piping configurations will have the same valves and strainers as bottom piping configurations.

Form C alarm contacts and shutdown input

A relay internal to the user interface is typically controlled by a user-defined alarm (malfunctioning fans,for example). Before an alarm is detected, the voltage on the COM terminal is routed to the NC terminal.When the alarm is activated, the relay is energized, causing the voltage on the COM terminal to berouted to the NO terminal. The NO and NC terminals may be connected to remote indicator lights, awarning buzzer, or another device to alert an operator to the presence of an alarm condition.

A remote disconnect switch may be connected to the shutdown inputs.

Leak detector port

Rope water detector (AP9325). Up to four optional rope waterdetectors can be installed in series. The rope water detectorconnects to the RJ-45 leak detector port located at the top of theinterface box.

See the Rope Water Detector installation sheet(supplied with the kit) for installation and setup information.

Temperature sensor

The remote temperature sensor monitors the room temperature,monitoring the environment surrounding the cooling equipment toensure that the conditioned air is cooling the area.

Note: The remote temperaturesensor comes coiled inside theequipment as shown, and must

be mounted as follows, or theequipment will not operate

properly.

Install the temperature sensor.

1. Route the rack temperature sensor through the hole ineither the top or bottom of the unit.

2. Route the sensor through either the top or the bottom

of the adjacent server rack.3. Secure the temperature sensor cable to the front door

of the adjacent server rack at multiple locations usingthe provided wire clips as shown. See Installationkit on page 3.

The sensors must be installed where lack of sufficientcooling air is most likely. The optimum position of therack temperature sensors will vary from installation toinstallation, but should be located in the airflow toallow accurate readings.Servers most likely to have insufficient air or inadequately cooled air due to the recirculation of

hot air from the hot aisle include:a. Servers positioned at the top of a rack.

b. Servers positioned at any height in the last rack at an open end of a row.c. Servers positioned behind flow-impairing obstacles such as building elements.d. Servers positioned in a bank of high-density racks.e. Servers positioned next to racks with Air Removal Units (ARU).f. Servers positioned very far from the equipment.g. Servers positioned very close to the equipment.
